Use bfd id to validate dwarf2 cache

Using a bfd pointer to validate the cache isn't very robust.  If a bfd
is closed somehow without clearing the cache, then it's possible that
another bfd is opened using the same memory and thus orig_bfd compares
equal to the new bfd.

* dwarf2.c (struct dwarf2_debug): Add orig_bfd_id.  Delete
orig_bfd.
(_bfd_dwarf2_slurp_debug_info): Validate stash with orig_bfd_id.
